i am VAS vendor and have deployed my server in one of the operator having ericsson switch. i am getting maximum fail calls in case of out dial, thats why i want to know the diffrent error logs for end of selection. by this i would be able to know thw exact reason (like subscriber is absent, switch off, out of coverage, number doesnt exsist, etc)
End of Selection cause codes helps to understand how a telephony session was released. The generated cause code will help with trouble shooting switch resources, circuits, connections, signalling, etc..
As EOS (cause codes) captures the nature of the call release it can be used as an input for any planned CEM system solution.
Information from the Network will need to be captured, stored and processed so that “insights” can be created.
